Hello, Maybe someone knows how to fix this problem. I'm using Macbook Pro 15" 2017 with Catalina and Parallels 15 pro. 1. I installed windows through Bootcamp, everything was working correctly. 2. Sometimes I need to work with windows at the same time, so I decided to use parallels and create virtualization from Bootcamp. To reach proper resolution etc I installed parallels tools. In parallels, everything is working correctly. 3. Sometimes I need to run Windows directly ( not through parallels ), and I found that Bootcamp drivers disappeared. I do not have got special keys from the keyboard, I can't open, Bootcamp option, I can't use right-click on the touchpad. I reinstalled my windows through Bootcamp a few times and I found that: - if I will set up parallels ( without installing parallels tools ) I can reopen windows directly and everything is working correctly. Unfortunately, resolution, the feeling is terrible. - after installation parallels tools, Bootcamp drivers disappearing I also tried to reinstall Bootcamp drivers directly in windows and it is not resolving the problem. I created a ticket, but since beginning of December support does not help me.
